Embodiment 1

[0046] Such as figure 1 As shown, it is a flow chart of a watermark adding method provided by the embodiment of this application. For the application scenario of VDI, the client can first apply for a virtual machine relying on the VDI desktop architecture, and use the client to operate the remote virtual machine In this way, the execution subject of the above watermark adding method may be an electronic device such as a remote server deployed by a virtual machine. The above watermark adding method specifically includes the following steps:

[0047] S101. According to the received watermark configuration information, add watermark content to the created layer to obtain a watermark layer; wherein, the transparency of the area where the watermark content is located in the watermark layer is lower than the first set value, except for the area where the watermark content is located The transparency of the area other than the second set value is lower than the second set value, and...

Embodiment 2

[0077] Such as image 3 As shown, it is a flowchart of a watermark analysis method provided in Embodiment 2 of the present application. For the application scenario of VDI, the execution subject of the above watermark adding method can be a client, or a remote server deployed by a virtual machine. and other electronic devices, in order to ensure the management authority of the watermark analysis operation, the embodiment of the present application may select a remote server as the execution subject, and the watermark analysis method specifically includes the following steps:

[0078] S301. Obtain an image to be analyzed;

[0079] S302. Traverse the pixels in the image to be analyzed, use the pixel value of the first pixel traversed as the reference pixel value, and continue to traverse the pixels in the image to be analyzed, and perform a judgment process: judge the pixel of the currently traversed pixel Whether the pixel difference between the value and the reference pixel v...

Embodiment 3

[0096] Such as Figure 5 As shown, it is a schematic structural diagram of the watermark adding device provided in Embodiment 3 of the present application, and the device includes:

[0097]The generating module 501 is configured to add watermark content to the created layer according to the received watermark configuration information to obtain a watermark layer; wherein, the transparency of the area where the watermark content is located in the watermark layer is lower than the first set value, except The transparency of the area other than the area where the watermark content is located is lower than the second set value, and the second set value is smaller than the first set value;

[0098] The fusion module 502 is configured to perform fusion processing on the watermark layer and the image to be processed to obtain a fused image; where there are distinguishing features between the fused image and the pixels at the position corresponding to the watermark content of the imag...

Abstract

The invention relates to the technical field of computers, in particular to a watermark adding method and device, an analysis method and device, electronic equipment and a storage medium, and aims toadd and analyze watermarks and save time and labor. The watermark adding method comprises the following steps: adding watermark content on a created layer according to received watermark configurationinformation to obtain a watermark layer; carrying out fusion processing on the watermark layer and the to-be-processed image to obtain a fused image, wherein the fused image and the to-be-processed image have a distinguishing feature between pixel points at a position corresponding to the watermark content.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to a watermark generation method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of computer technology and network technology, the application of digital watermark is becoming more and more extensive. For example, for the application field of the Internet, in order to prevent illegal copying and tampering of images displayed on Internet sites, watermarks are usually added to the images. [0003] In order to take into account the user experience and the reasonable use of watermarks, a blind watermark generation scheme that can hide the watermark layer is provided in related technologies. This scheme first converts the original image space domain data into frequency domain data, and then according to The watermark information (such as user identity information) is adjusted to the frequency domain data, and ...
